Transparency note: This research-based review uses Sennheiser’s official Accentum Plus page and instruction manual. We did not perform hands-on sound, ANC, microphone, battery or comfort testing. Published performance statements are treated as manufacturer claims, while specifications are used for practical comparison.
Quick answer: Sennheiser Accentum Plus is a light, long-lasting wireless ANC headphone. It weighs about 227 g, supports aptX Adaptive and two active Bluetooth connections, and is rated for up to 50 hours with ANC enabled. Its case is strongest for commuters who want flagship-style essentials without flagship weight or price.
Key specifications
- Closed-back circumaural design
- 37 mm dynamic drivers
- Approximately 227 g
- Bluetooth 5.2 with SBC, AAC, aptX and aptX Adaptive
- Two simultaneous active connections
- Up to 50 hours with ANC active
- Ten-minute quick charge for up to five hours
- USB-C and 3.5 mm listening options
Battery is the clearest advantage
Sennheiser specifies up to 50 hours of Bluetooth playback with ANC active under its stated test conditions. That is unusually strong because the headline does not require disabling noise cancellation. The manual lists approximately 3.5 hours for a full charge, while a ten-minute top-up is promoted for up to five hours.
Actual runtime varies with volume, codec, calls, temperature and battery age. Still, the margin over many 24- to 30-hour rivals is meaningful for travel. Long endurance also reduces charging cycles, although it does not eliminate eventual lithium-ion degradation.
Comfort and controls
At about 227 g, Accentum Plus is lighter than many premium ANC competitors. That reduces one source of fatigue, but clamp, pad opening, glasses and heat remain personal. A light headphone can still be uncomfortable if the geometry does not fit, so an extended trial is important.
A touch surface handles common playback and call commands, with a physical multifunction button for selected functions. Gesture controls create a clean interface but are not ideal for every user, particularly with gloves. Buyers who prefer dedicated buttons should compare Bose or Beats.
Sound and connections
The 37 mm driver and published 10 Hz–22 kHz response do not reveal tonal balance. Sennheiser’s descriptions of detailed sound remain marketing until supported by independent measurement or listening. The Smart Control app provides EQ and sound-personalisation options, which are more useful than broad frequency-range numbers.
aptX Adaptive can adjust quality and latency on compatible sources, while aptX, AAC and SBC broaden support. Codec availability depends on the transmitting device; Apple mobile devices generally use AAC. Multipoint allows two active connections, useful for switching between a laptop and phone.
Accentum Plus supports listening through USB-C and an analogue cable. That gives it more source flexibility than charging-only USB-C models. Buyers should check the manual for how ANC, controls and battery behaviour differ between connection modes.
Adaptive ANC and calls
Adaptive ANC is intended to vary cancellation according to ambient conditions, with Transparency mode for awareness. No processor name or mode label establishes performance against aircraft rumble, speech or wind. Current controlled attenuation tests remain the best comparison.
The manual specifies four omnidirectional MEMS microphones in a beamforming arrangement for speech. That is a design fact, not proof of natural voice quality. Frequent callers should listen to samples recorded in quiet, traffic and wind.
Who should buy it?
Choose Accentum Plus if low weight, long ANC-on battery, modern codecs, multipoint and wired flexibility are priorities. Skip it if you want luxury materials, fully physical controls or a confirmed sport-protection rating. Its value should be judged against current sale prices, not list price alone.
Alternatives and verdict
The JBL Tour One M3 offers more travel extras, the Sony WH-1000XM5 has a mature mainstream feature set, and the Soundcore Space One Pro folds into a smaller package.
Sennheiser Accentum Plus is attractive because its strengths are practical rather than decorative: 227 g, a 50-hour ANC rating, two-device connectivity and multiple wired paths. Touch controls and fit are the main personal checks. At a competitive price, it is one of the more rational travel-headphone shortlists.
